[media] redrat3: new rc-core IR transceiver device driver

This is a new rc-core device driver for the IR transceivers made by
RedRat Ltd. (http://redrat.co.uk/). It started out life as an
out-of-lirc-tree lirc driver, maintained in its own repo on sourceforge,
by Stephen Cox. He started porting it to what was then ir-core, and I
finally picked it up about two week ago and did a fairly large overhaul
on it, and its now into a state where I'm fairly comfortable submitting
it here for review and inclusion in the kernel. I'm claiming authorship
of this driver, since while it started out as Stephen's work, its
definitely a derivative work now, at 876 lines added and 1698 lines
removed since grabbing it from sourceforge. Stephen's name is retained
as secondary author though, and credited in the headers. Those
interested in seeing how the changes evolved can (at least for now) look
at this branch in my git tree:

http://git.kernel.org/?p=linux/kernel/git/jarod/linux-2.6-ir.git;a=shortlog;h=refs/heads/redrat3

That won't be around forever though, and I'm doing this as a single
commit to go into mainline. Anyway...

I've successfully tested in-kernel decode of rc5, rc6 and nec remotes,
as well as lirc userspace decode of rc5 and rc6. There are still some
quirks here to sort out with rc5 lirc userspace decode, but I'm working
with the RedRat folks themselves to figure out what's going on there
(rc5 lirc decode works, but you only get an event on key release --
in-kernel rc5 decode behaves perfectly fine). Note that lirc decode of
rc6 is working perfectly. Transmit is also working, tested by pointing
the redrat3 at an mceusb transceiver, which happily picked up the
transmitted signals and properly decoded them.

There's no default remote for this hardware, so its somewhat arbitrarily
set to use the Hauppauge RC5 keymap by default. Easily changed out by
way of ir-keytable and irrelevant if you're using lircd for decode.

[media] rc: add locking to fix register/show race

When device_add is called in rc_register_device, the rc sysfs nodes show
up, and there's a window in which ir-keytable can be launched via udev
and trigger a show_protocols call, which runs without various rc_dev
fields filled in yet. Add some locking around registration and
store/show_protocols to prevent that from happening.

The problem manifests thusly:

Continuing with IR transmit after resuming from suspend seems fairly
useless, given that the only place we can actually end up suspending is
after IR has been send and we're simply mdelay'ing. Lets simplify the
resume path by just waiting on tx to complete in the suspend path, then
we know we can't be transmitting on resume, and reinitialization of the
hardware registers becomes more straight-forward.

ite-cir driver in 2.6.39, but stops working after a suspend/resume
cycle. Its fixed by simply reinitializing registers after resume,
similar to what's done in the nuvoton-cir driver. I've not tested with
any other ITE variant, but code inspection suggests this should be safe
on all variants.

[media] V4L: mt9m111: fix pixel clock

This camera driver supports only rising edge, which is the default
setting of the device. The function mt9m111_setup_pixfmt() overwrites
this setting. So the driver actually uses falling edge.
This patch corrects that.

The initial version of this patch (commit

 * It didn't correctly calculate the size of the YUV buffer for 4:2:2,
   resulting in capture sometimes being offset by 1/3rd of a picture.

 * There were a lot of variables duplicating information the driver
   already knew, which have been removed.

 * There was an in-kernel format conversion - libv4l can do this one,
   and is the right place to do format conversions anyway.

 * Some magic numbers weren't properly explained.

to do.

[media] gspca/stv06xx_pb0100: Don't potentially deref NULL in pb0100_start()

usb_altnum_to_altsetting() may return NULL. If it does we'll dereference a
NULL pointer in
drivers/media/video/gspca/stv06xx/stv06xx_pb0100.c::pb0100_start().
As far as I can tell there's not really anything more sensible than
-ENODEV that we can return in that situation, but I'm not at all intimate
with this code so I'd like a bit of review/comments on this before it's
applied.
Anyway, here's a proposed patch.

[media] rc-core: add trailing silence in rc-loopback tx

If an IR command is sent (using the LIRC userspace) to rc-loopback
which doesn't include a trailing space, the result is that the message
won't be completely decoded. In addition, "leftovers" from a previous
transmission can be left until the next one. Fix this by faking a long
silence after the end of TX data.
